Examples of such applications include distributed file systems and master/slave data replication. We present Flease, an algorithm for decentralized and fault-tolerant lease coordination in distributed systems. Our algorithm allows the processes competing for a resource to coordinate exclusive access through leases among themselves without a central component. The resulting system easily scales with an increasing number of nodes and resources. We prove that Flease ensures exclusive access, i.e. guarantees that there is at most one valid lease at any time.}, language = {en} } @inproceedings{StenderKolbeckHoegqvistetal.2010, author = {Stender, Jan and Kolbeck, Bj{\"o}rn and H{\"o}gqvist, Mikael and Hupfeld, Felix}, title = {BabuDB: Fast and Efficient File System Metadata Storage}, booktitle = {Storage Network Architecture and Parallel I/Os, IEEE International Workshop on}, publisher = {IEEE Computer Society}, address = {Los Alamitos, CA, USA}, doi = {10.1109/SNAPI.2010.14}, pages = {51 -- 58}, year = {2010}, language = {en} } @inproceedings{SteinkePeterBorchert2010, author = {Steinke, Thomas and Peter, Kathrin and Borchert, Sebastian}, title = {Efficiency Considerations of Cauchy Reed-Solomon Implementations on Accelerator and Multi-Core Platforms}, booktitle = {Symposium on Application Accelerators in High Performance Computing (SAAHPC)}, address = {Knoxville, USA}, year = {2010}, language = {en} } @inproceedings{StenderHoegqvistKolbeck2010, author = {Stender, Jan and H{\"o}gqvist, Mikael and Kolbeck, Bj{\"o}rn}, title = {Loosely Time-Synchronized Snapshots in Object-Based File Systems}, booktitle = {Proceedings of the 29th IEEE International Performance, Computing, and Communications Conference}, publisher = {IEEE Computer Society}, doi = {10.1109/PCCC.2010.5682311}, year = {2010}, language = {en} }
